头足类动物如章鱼和乌贼，能够通过复杂的神经肌肉系统精确控制皮肤颜色、纹理和整体形态，实现卓越的伪装和通讯能力。然而，在合成材料中实现这种多特征动态协调控制一直是一个重大挑战。现有的材料系统，如纳米复合材料、形状记忆聚合物和液晶弹性体，往往只能在某一方 ...

4D打印是一种基于3D打印发展而来，将智能材料和力学设计融入打印过程的新型制造技术。在光、热、电、磁等外界环境刺激下，4D打印结构可随时间产生形状或功能的改变，在生物医疗、航空航天等领域有着广阔的应用前景。目前，能实现4D打印的材料主要局限于水凝胶、形状记忆聚合物和液晶弹性体等智能软材料，而对于陶瓷类硬质材料的4D打印仍存在诸多技术瓶颈。现有的陶瓷4D打印主要基于墨水直写工艺，且需模具实现结构预编 ...

Skylar Tibbits Shares His Insights on the Biotechnology and Medical Applications of 4D Printing One of the most rapidly developing technologies that is already affecting a wide range of research and ...

In his PhD research at Utrecht University and UMC Utrecht, Marc Falandt developed biomaterials whose properties can be adjusted even after they have been 3D-printed, effectively adding a fourth ...

STAFFORD, England—A new manufacturing technique brings a fourth dimension to additive manufacturing through the use of "smart polymers" that can be programmed to remember shapes when they are printed, ...

It might seem like there’s a typo in the title, but 4D printing stocks are a real industry emerging right now. But what is 4D printing, other than just 3D printing in an extra dimension? Well, in this ...

Though the practice of 3D printing is still firmly entrenched in its journey from fledgling idea to emerging technology, news out of Harvard’s Wyss Institute this week proves innovation waits for no ...

(Nanowerk Spotlight) Compared to creating static objects with 3D printing, 4D printing systems add time as the fourth dimension to 3D printing: 4D printing allows a 3D printed structure to change its ...

Frost & Sullivan’s new report sheds light on the trends facing 4D technology and the markets it’s looking to serve in the next few years. 4D printing develops materials that can change properties and ...

Although 4D printing is considered very promising for various biomedical applications – such as tissue scaffolds, neural scaffolds, grafts and stents, cardiac patches and valves, even bionic ...

It may seem distinctly low-tech compared to some of the many technology trends I write about, but 3D and 4D printing will have very wide applications – and could be particularly powerful when combined ...
